ResumoTHE summer of 1929 was extremely unfavourable for navigation in the East Greenland pack-ice. Adverse conditions kept the ice pressed against the coast, and lanes or leads of water along which a ship might have passed were rarely found (Plate 3). The Cambridge Expedition was thus detained among the ice-floes for four weeks. During this time it was noticed that in many cases fine mud rested upon the irregular surface of the ice. A more careful examina? tion was then made of mud on other floes, and finally Dr. J. F. Varley obtained a number of shells.* The object of this paper is to show how shallow-water shells associated with clays may be transported by ice for several hundred miles, and to emphasize the possible bearing of this fact upon the question of the origin of certain Pleistocene glacial clays containing derived shells.
